Acquisition of Equipment for Measuring Magnetic Properties of Rocks

9633500 Herrero-Bervera这笔赠款提供60,000美元，作为为夏威夷大学古地磁学实验室购买配备直流鱿鱼的2-G超导岩石磁强计的费用的一半。夏威夷大学购买了最先进的SRM，这将为研究地球地磁场的行为提供对弱磁化海洋沉积物中记录的相对古强度的高灵敏度测量。此外，与继续运营过时的SCT SRM相比，由于与其运营相关的液氮和氦的高蒸发率，其运营成本降低，从长远来看，将有利于夏威夷古地磁研究计划的健康发展。这项收购为古地磁研究提供了宝贵的机构和区域资源，其中将包括对地磁场行为、海洋和湖泊磁地层以及在火成岩中观察到的极性转变的研究。***

9633500 Herrero-Bervera This grant provides $60,000 as one-half support of the costs of acquiring a 2-G superconducting rock magnetometer (SRM) equipped with DC SQUIDS for the paleomagnetics laboratory at the University of Hawaii. The acquisition of a state-of-the-art SRM at the University of Hawaii will provide for high sensitivity measurements of the relative paleointensity recorded in weakly magnetized marine sediments for research on the behavior of the Earth's geomagnetic field. Furthermore, its reduced operating costs relative to continued operation of their antiquated ScT SRM, due to the high boil off rate of liquid nitrogen and helium associated with its operation, will be economically beneficial in the long run for the health of the paleomagnetic research program at Hawaii. This acquisition provides a valuable institutional and regional resource for paleomagnetic studies which will include studies of geomagnetic field behavior, marine and lacustrine magnetostratigraphy and polarity transitions observed in igneous rocks. ***
